Abstract
The present invention discloses a fluid ejection apparatus in which fluid is uniformly ejected from all nozzles. The disclosed fluid ejection apparatus includes a main body coupled to a fluid supply line and having a fluid inflow space portion and having a plurality of nozzles spaced apart from each other in the longitudinal direction, And a fluid discharging portion provided in the fluid guiding portion and discharging the fluid introduced into the fluid guiding portion to the fluid pressure diffusing portion . Therefore, the present invention is advantageous in that the fluid uniformly diffuses from the nozzle close to the fluid supply line or the nozzle away from the fluid supply line, because the pressure of the fluid flowing into the body from the fluid supply line is uniformly diffused in the interior of the body by the fluid- .
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fluid ejection apparatus, and more particularly, to a fluid ejection apparatus that allows fluid to be uniformly ejected from all nozzles.
In general, the nozzles are used for jetting liquid, and can be classified into an internal mixing type spraying nozzle and an external mixing type spraying nozzle depending on the position where the jetted liquid is mixed with air. These nozzles are used in various fields throughout the industry.
Such liquid spray nozzles are often used in processes such as deposition, lithography, etching, chemical / mechanical polishing, cleaning, and drying when producing semiconductor substrates.
In addition, a conventional liquid injection nozzle is formed in a tubular shape in which a fluid is introduced through a fluid supply line so that fluid can be injected into a wider area, and a plurality of nozzle heads are coupled to the tubular housing in a spaced apart manner.
However, in the above-described conventional liquid injection nozzle, there is a problem in that the pressure near the fluid supply line is large and the injection amount of the fluid jetted from the nozzle head and the jetting range can not be made uniform.
Therefore, there is a need to improve this.
On the other hand, Korean Patent No. 10-0841410 (filed on June 19, 2008) discloses a " two-phase fluid injection nozzle for fluid mixing ".
It is an object of the present invention to provide a fluid ejection device which is created by the above-described necessity and in which the fluid can be uniformly ejected from all the nozzles.
According to an aspect of the present invention, there is provided a fluid ejection apparatus including: a main body coupled to a fluid supply line, having a fluid inflow space and a plurality of nozzles spaced apart from each other in the longitudinal direction; A fluid guiding part inserted into the fluid inflow space part to be supplied with fluid from the line and coupled to the main body and forming a fluid pressure diffusion part in the fluid inflow space part in a pair with the main body; And a fluid discharging portion for discharging the fluid flowing into the guide portion to the fluid pressure diffuser.
The main body includes a first pipe member to which the nozzle is fastened, a connection joint to which one end of the first pipe member is connected, and which connects the fluid supply line and the fluid guiding portion, And a cap member sealing the end portion.
The fluid guide portion may include a second pipe member inserted into the first pipe member such that one end thereof is joined to the connection joint, and the fluid discharge portion is formed, and the second pipe member is supported by the first pipe member And a support member provided at the other end of the second pipe member.
The fluid discharge portion may be an enlarged hole portion extending from a central portion to a second end portion of the second pipe member.
The fluid discharge unit may further include a fluid discharge hole portion formed at equal intervals along the longitudinal direction of the second pipe member.
The fluid discharge hole portion gradually increases in diameter from one end to the other end of the first pipe member.
As described above, the fluid ejecting apparatus according to the present invention differs from the prior art in that the pressure of the fluid flowing into the body from the fluid supply line is uniformly diffused in the interior of the body by the fluid guiding portion, And the nozzle spaced far from the fluid supply line uniformly inject the fluid.
